Plant issue

So I noticed that the plant has been yellowing through the middle and the top. Growing in a soil/clay ball mix. Ferts every three days. Regular water the rest of the time. I have a fan blowing up, under the plant and it seems to make the soil dry out, completely, every day, so I've had to water it every day (not sure if that may be the issue?).

My question is... any idea what I may be doing wrong and, from the flower image, can you tell how long before I can harvest? I want to harvest before the plane dies on me, but I don't want to harvest too soon.

Overall they look pretty good! Are you feeding calmag? It's possible you have a slight magnesium deficiency. It could also be that those fan leaves have reached the end of their lifetime.

It's starting to get quite bad. Here is how it looks, today:
Also, from the pic of the flower, can you tell how much longer I have before I harvest?
Thanks in advance!

Based on those pics, I’d say you have either too much or not enough phosphorus. The browning along the leave margins is pretty indicative of a phosphorus issue. What are you feeding and how often?

I have an NPK stuff that I give, about every 3 days. It is a powdered mix and I add a quarter tsp to 2 liters of water, then water with that every third day. I water with plain water in between, as needed.
I'll see if I can find the brand...

Here is the stuff. I put a quarter tsp in 2 liters of water.

That’s some pretty hot stuff, for flowering it’s a bit high in N, but it’s got plenty of P, maybe too much, if it was me I’d cut back on the nutes fo 1/2 strength for a week and see what happens. The problem is, the symptoms of too much P and too little are very similar looking.

Edit: the wild card is your grow media, I’ve never dealt with soil/clay hybrid soil, so I don’t know if you treat it like hydro or soil. That nute is synthetic, so somewhere along the grow you may need to flush the media to remove the chelating salts.

I will try switching to water for a bit and see if cleaning it out helps.
By the way, can you give me your best guess as to how much longer I have before harvest, based on the flower pic,a few posts back?

Your plant is way overfed. What size pot, you're only using 2 liters a watering? Can you please describe your soil and whats in it in percentages if possible. Does any water come out the bottom when you water? I would stop with the feed for at least a week that stuff is really potent. Then feed it half dose of that once a week.

Whats strange is only your main cola is having this issue. Are you using UVB lights? What is your light and how many actual watts is it? How close to the top of the cola is the light. You're plant has probably three weeks left.

This is the light I bought at the recommendation of one of the members on this site:

For soil, I bought a bag of "Pro-Mix HP High Porosity Professional Growing Medium w/ Mycorrhizae" and mixed in a small amount of clay pebbles, growing medium to help with drainage. The pot is slightly smaller. Maybe 2 gallon? I will include a pic of it (Please excuse the messy tent. This was when I first moved the seedling over and before I cleaned it out!). Water does come out at the bottom of the pot when I water.

The nutes are a powder in a container and you mix it with the water, but the amount you add to the water is so small that it is supposed to be safe to use with every watering. Of course, that is what I was told by the lady at the grow store. She could have just been trying to sell me those nutes. lol. Because I had this problem the last time I grew a plant (This is number 2 now), I have to wonder if it IS the nutrients? That or pot is too small?

Thats why right there. Your pot is super small for that size plant. Watering every day at this point is a good idea. Water till there is a little runoff. You may need to water twice a day too, I would check the pot weight frequently.

Now with that feed and your pot size this is how you'll do it on a seven day schedule

Feed once every other day at 1/4 strength that should be perfect. Then just plain water the rest of the time. For right now dont feed it anything for a about 4 or 5 days just plain water. After that start the feed regimen. Learn to read the plant too. If it has super dark green leaves with a little claw or tips burning then its too much. Hope that helps.

Helps so much!
What size pot should I be looking for, for my next grow? The problem I have is the tent is short so I can't go any taller....

5 gallon minimum (which is really only about 4 gallons). Do Low stress training to keep the plants short, and/or grow Indica's or Autos, which tend to be shorter in stature.

Thank you so much for the help. You guys, and this forum, are amazing! I hope, some day to know enough to be able to help out others, here.

So... most of the fan leaves have died.. plant looks like it's not got long. Maybe a week, tops, before it has died. Can I harvest the buds as they are, or have I lost the whole crop? How much longer before this looks ready(minimum)?

Okay, 90% of the fan leaves are now dead and gone. Plant is dying, fast. I noticed that the soil is remaining wet and I haven't had to water in three days (previous to this, it was dried out, like desert dry, every day).
Do I risk losing the flowers if I continue to wait? From the previous image, can you tell how much longer?

I'm not sure what to do!

We need a picture to see what's going on and better answer you

what have you changed that caused the leaves and 'plant' to start to die?

I think we determined that the pot size was the issue. It's only a 2 gallon. So at this point, I'd just like to save what I can and buy a larger pot for the next plant.
Can I harvest, looking at the current state of the flower? Would it be a waste? Should I keep waiting or will the buds die along with the leaves?

Keep a close eye on it, but the fan leaves and some of the sugar leaves dying won't kill the plant, but watch closely for mold/fungus which can develop on the dead leaves. Looking at the bud pics it's not ready. When a plant is rootbound the roots can only support X amount of foliage, after that, for every new leaf/growth, something old had to die!

Thanks so much for the help!
Here is the current pic of the top bud. How much longer would you guess it has and should I wait that long?
To let you know, I have a garbage bag full of all the dead leaves and the ones that are still attached are browning and dying quickly.
